Mass polio vaccination underway in Bangladesh

More than 700,000 volunteers have fanned out across Bangladesh to help vaccinate 24 million children against polio.

Despite Bangladesh being unofficially polio-free since 2000 there have been signs the virus is making a comeback in the country.

A new case was identified in January, prompting authorities to start new a vaccination drive for children under five.

Parents are being encouraged to take their children to thousands of health centres including mobile teams set up at bus and train stations.

Health teams will also visit brothels and slums.
